#Motivation We got a intercom system at our new office, but everytime a customer or colleague wants to come in, someone has to stand up and hurry to the opening button. To conquer this problem we used a Raspberry Pi with an Apache2 Webserver and a little servo.
#Setup
##Raspberry Pi
At first of all we had to get the Pi to boot up, you can find a good tutorial here
After the first boot we installed apache2
sudo apt-get install apache2
Next copy all the files from this repo into the 'www' folder of apache, in our setup it was
/var/www/
After that you should see the door opening website if you open up your browser and type in the IP of your raspberry in your network, for example
http://192.168.0.10/
##Pinout
-
Servo:
- Power - Pin 2
- Ground - Pin 6
- Signal - Pin 12
-
Led:
- Don't forget a resistor (470 Ohm) between Ground and Cathode!
- Cathode - Pin 6
- Anode: - Pin 22
##How it works
- Apache is used to have a graphical interface programmed in HTML
- In this index.html is a simple button which triggers a javascript (jquery) clickevent
- The javascript function loads a PHP-Script (scripts/open.php)
- open.php executes a Python-Script (scripts/servo.py) which turns the servo and pressed the door opening button
